Mutation: John has the strength and endurance beyond that of most mutants. He can barely be hurt, an enormous, invulnerable monster. Theoretically he is capable of benchpressing the Empire State Building.

History: Abandoned at birth, John was raised in foster care by a man named Nathaniel Essex, also known as Mister Sinister, who recognized John's "Genetic Superiority." Ever since, he has been the main brute force of Sinister's band of so-called genetically superior mutants, called the Marauders.
